Well, first of all I would take them to your pharmicist and ask him about it. I had been getting white,round, lisinopril and then one time I got the same prescription and they were round and blue. I asked the pharmacist about it and he said it was the same medication but had come from a different company. Now the Lisinopril I've been getting is still round but a light tan color. I was told by the pharmacy that they purchase the cheapest generics available each month. Different companies make different looking pills sometimes. I would always ask if in doubt because people do make mistakes sometimes.
